Question

a = 17 nhân mo ngoac 1313/5151 + 1111 phần 3434 đóng ngoặc chia 177 phần 12

Answer 1

\(A=17\cdot\left(\frac{1313}{5151}+\frac{1111}{3434}\right)\div\frac{177}{12}\)

\(A=17\cdot\frac{59}{102}\div\frac{177}{12}\)

\(A=\frac{59}{6}\div\frac{177}{12}\)

\(A=\frac{2}{3}\)

Answer 2

\(a=17.\left(\frac{1313}{5151}+\frac{1111}{3434}\right):\frac{177}{12}\)
\(a=17.\left(\frac{13}{51}+\frac{11}{34}\right):\frac{177}{12}\)
\(a=17.\frac{59}{102}:\frac{177}{12}\)
\(a=\frac{59}{6}:\frac{59}{4}\)
\(a=\frac{2}{3}\)
thấy dúng thì k mik nha!!
